Title: Training device by automatic playing piano
Inventor: MATSUNAGA HIROSHI
IPC: G10H1/00
Filed: 1992-02-14
Abstract: PURPOSE:To enable an effective self-practice by storing performance information that a pupil inputs, comparing this performance information with example information at a specific check point, and generating a performance correction indication if there is a discrepancy. CONSTITUTION:When the pupil plays on the automatic playing piano, a performance information storing means M2 stores key depression information and key releasing information in a performance information storage means M1 as performance information following a flow of the performance. A discrepancy mode judging means M5 compares the performance information which is generated by the pupil and stored in the performance information storage means M1 with the example performance information stored in an example performance information storage means M4 at the specific check point to judge the mode of the discrepancy between both the pieces of performance information. When there is the discrepancy between both the pieces of performance information, a correction indication generating means M7 reads a corresponding arithmetic correction indication out of a correction indication storage means M6 storing the performance correction indication and outputs it at the check point where the discrepancy is present.
